Lake Shore exhibiting solutions for optical device research at SPIE conference
Lake Shore Cryotronics Exhibiting at SPIE Optics and Photonics

Lake Shore Cryotronics will showcase cryogenic probe stations and other solutions optimized for optical material and device research at next week’s SPIE Optics + Photonics exhibition in San Diego.

On display will be the TTPX cryogenic probe station, an affordable tabletop station for temperature-dependent measurements of full and partial wafers up to 51 mm (2 in) in diameter. Lake Shore’s premium design for electro-optical materials characterization, the TTPX supports optional backside optical illumination of a sample (ideal for examining photosensitive materials with topside metallization).

Lake Shore offers a full range of stations for performing electro-optical, DC, RF, and microwave measurements of materials and devices, including photovoltaic materials and semiconductor optoelectronic devices, in a high-vacuum environment at temperatures as low as 1.6 K. Stations can be ordered with integrated magnets, along with fiber optic probe arms and feedthroughs for optoelectronics research, and also load-lock assembly and suitcase transfer options for air-sensitive material characterization.

Also on display in Lake Shore’s booth: the unique, modular MeasureReady™ M81-SSM synchronous source measure system, which can be used to provide an excitation source for measurements performed in a cryogenic probe station as well as a Lake Shore Environment by Janis cryostat.

The M81-SSM supports up to three remote-mountable source and three measure modules per single M81-SSM-6 instrument, with the source modules capable of providing combined DC+AC voltage/current outputs with low noise levels for highly sensitive device characterization.

Owing to its modular architecture, modules can be mounted directly on the probe station or cryostat, minimizing noise and unwanted effects from cabling and wiring to the sample. Similar setups can be used for other optical experiments, such as external quantum efficiency (EQE) measurements of solar cell and photodetector devices, and light-current-voltage (LIV) testing of laser diodes and LEDs.

Also at SPIE Optics + Photonics, Lake Shore will discuss the company’s:
